ALMA Discovers Rotating Infant Galaxy with Help of Natural Cosmic Telescope

Due to the gravitational lensing effect by the galaxy cluster, the image of RXCJ0600-z6 was intensified and magnified, and appeared to be divided into three or more parts.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only seven percent of its present age. Thanks to assistance by the gravitational lens effect, the team was able to explore for the first time the nature of small and dark “normal galaxies” in the early Universe, representative of the main population o

April 22, 2021 by archyde MADRID, Apr 22. (EUROPA PRESS) – Observations with the ALMA telescope have revealed a young spinning galaxy one hundredth the size of the Milky Way in
a time when the Universe was only 7% of its current age. Taking advantage of the effect of a gravitational lens,
astronomers were able to study for the first time the nature of small, dark “normal galaxies” in the early Universe, representative of the main type of galaxy existing at the beginning. These observations help to greatly improve our understanding of the early stage of galactic evolution. “Many of the galaxies in the early Universe were so small that their brightness is much lower than the minimum brightness captured by the largest telescopes currently existing on Earth and in space, which is why it is so difficult to study their properties and internal structure” , Explain
